BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates generally to an apparatus for laminatingan object with a fiber tow. More particularly, the present inventionrelates to an apparatus for laminating an object with a fiber tow, theapparatus being configured for simultaneously laminating a surface of anobject with first and second fiber tows that may be configured to bedifferent from each other.

Description of Related art

In general, in the case of an automated fiber placement (AFP), which isa method whereby an object is laminated with a fiber tow, the AFP methodis designed to laminate a surface of the object with one type of fibertow t. Thus, when it is desired to laminate an object with differenttypes of fiber tows, the object is first laminated with one type offiber tow and then a creel on which the first fiber tow is wound isreplaced with an additional creel on which a different type of the fibertow is wound. Then, the object is laminated with the different type ofthe fiber tow.

The AFP method is problematic in that it is time consuming, thus leadingto a reduction in productivity. Thus, a study of an apparatus forlaminating an object with a fiber tow, wherein the apparatus is capableof simultaneously or selectively laminating objects with different typesof fiber tows is required.

With reference to FIG. 4, when the holding part 340 is configured to beoperated to hold the first fiber tow 10 or the second fiber tow 20, thefirst fiber tow 10 or the second fiber tow 20 fails to be wound relativeto the laminating roller 310. Accordingly, the first fiber tow 10 or thesecond fiber tow 20 is prevented from being laminated on the surface ofthe object 1. Thus, by selectively adjusting an operation of the holdingpart 340, the first fiber tows 10 and the second fiber tows 20 can besimultaneously laminated on the surface of the object 1, or only one ofthe first and second fiber tows 10 and 20 can be laminated on thesurface of the object 1.

Thus, although the laminating roller 310 moves relative to thesurface of the object 1, only the first fiber tows 10 can be laminatedon the surface of the object 1 without lamination of the second fibertows 20.

With reference to FIG. 5, in the exemplary embodiment, the laminatingroller 310 is separated into a first laminating roller 311 on which thefirst fiber tows 10 are wound and a second laminating roller 312 onwhich the second fiber tows 20 are wound; the roller support frame 320is configured with a first roller support arm 321 that is connected tothe first laminating roller 311 and supports the rolling motion of thefirst laminating roller 311 in the direction perpendicular to thelaminating direction of the first fiber tows 10, and a second rollersupport arm 322 that is connected to the second laminating roller 312and supports the rolling motion of the second laminating roller 312 inthe direction perpendicular to the laminating direction of the secondfiber tows 20; and the fixing frame 330 is configured with a firstfixing arm 331 to which the first roller support arm 321 is fixed, and asecond fixing arm 332 to which the second roller support arm 322 isfixed.

More in the exemplary embodiment, the first fixing arm 331 and thesecond fixing arm 332 may independently move in upward and downwarddirections.

The laminating roller 310 may be separated at a center thereof and maybe divided into the first laminating roller 311 and the secondlaminating roller 312. The first laminating roller 311 on which thefirst fiber tows 10 are wound, and the rolling motion thereof issupported by the first roller support arm 321, and the first rollersupport arm 321 is fixed to the first fixing arm 331. The secondlaminating roller 312 on which the second fiber tows 20 are wound, andthe rolling motion thereof is supported by the second roller support arm322, and the second roller support arm 322 is fixed to the second fixingarm 332.

Accordingly, the lamination device 300 is separated based on the firstfiber tows 10 and the second fiber tows 20, and the first fixing arm 331and the second fixing arm 332 are connected to the apparatus body to bemovable in upward and downward directions. Thus, it becomes possible toselectively laminate the surface of the object 1 with only the firstfiber tows 10 or the second fiber tows 20.

For example, when it is desired to laminate the surface of the object 1with the first fiber tows 10, the second fixing arm 332 is controlled tomove upwards such that only the first laminating roller 311 movesrelative to the surface of the object 1. Thus, it becomes possible tolaminate the surface of the object 1 with only the first fiber tows 10in accordance with the rolling motion of the first laminating roller311.
